The application of suction to the lower end of thetube 3 simultaneously with the application of pressure upon the air in the upper portion of the cas: ing 1 serves to in part extract the milk from the teat l4 and to remove the milk thus extracted,'fron1 the milking device into any suitable receptacle, which receptacle may be a tank from which; the air isconStantlyfex:

haust-ed by suitable ineans, not shown While I have shown my inventiolr n the particularembodiment herein d sclosed, I

'do not, however, limit myself to this con 'struction, but desire :to claimany equivalent that will suggest itself 'to those skilled in the art. I

I claim 1. In a milking device, a casing, a flexible tube disposed in said casing, saidcasing being'fiared at one end to form an annulartube being'adapted contract before air is admitted between the lower 7 half of said tube and said casing.

2. In a milking device, a casing, a flexible tube disposed in said casing, said casing being flared at one end to form an annular chamber around the'upper end of said tube; the:1ower'end of said tube fitting snugly against said casing,and a connection Where: by a source of air supply may have communication with said annular chamber, substantially as described. 1

v 3. In a milking device, the combination of a casing, a flexible tube disposed in saidcasing, there being 'normally an annular chamber between the casing and the upper portionof said tube, thevlower portion of saidlt'ube fitting snugly against's'aidi casing, and a connection whereby a-sourceot pneumatic pulsations may communicate with said annular chamber, substantially as described.

4. In a milking device, a substantially funnel-shaped casing, a substantiallyconeshaped flexible tube disposed within, said funnel-shaped casing,-said flexible tube'normally fittingsnuglyagainstthe lower ortubular portion ofthe funnel-shaped casing,-

there being normally an annular chamber between the said flexible tube and the upper or body portion of the funnel-shaped casing,

and means for connecting said annular chamber with a source of pneumatic pulsations.

'5, In a milking device, a casing consisting ofa'lower conical portion and a substantially bowl-shaped upper portion, a cone shaped flexible tube disposed in said casing, said tube normally fitting snugly against the said conical lower portionjof said casing, there being 'normally an annular chamber betweenthe bowlshaped portion of,thecasing and saidfiexible tube, meansflior con-- nect ng sald annular chamber with a source of pneumatic pulsations, and means for retaining the device 'in operative position.
